DIE-STOCK.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed August 13, 1906- Serial No. 330.379.

To all whom it may concern:

Be it known that I, SEVERIN JoRGnNsEN, a citizen of the United States,residing at Arcata, in the county of Humboldt, State of California, haveinvented certain new and useful Improvements in Die-Stocks; and

I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention has relation to pipe roaming and threading implements.

It is the object of the invention to provide an implement of the kindmentioned that shall embody in its construction rotary adjustable dieshaving cutting faces located at varying distances from their axes forthreading pipes of different sizes or diameters.

It is a further object of the invention to provide improvements in areaming and threading implement that shall have its efficiencyadjustability and gen'eral utility enhanced, to the ends of improvingits effects, rendering it more convenient of operation and adjustment,and saving time and labor through its employment.

The invention is clearly and fully portrayed in the annexed drawingsforming a part of this specification, in View of which the inventionwill first be described in detail and then be pointed out in thesubjoined claims.

Of the said drawings:-Figure 1 is a plan of the implement. Fig. 2 is aside elevation. Fig. 3 is an end View. Fig. 4 is a longitudinal sectionin the plane 44 of Fig. 3.

Similarnumerals of reference designate the same parts or features, asthe case may be wherever they occur.

In the drawings 10 designates the stock or frame which is provided withthe usual central opening, and is provided on its upper side with a yoke11, for supporting the reamer, 12, through the medium of its stem, 13,adjustable'vertically in the yoke and held in adjusted position by meansof the set-screw 14. The yoke is provided at its lower end withlaterally extended feet 15 that are bolted to the stock. The stock isprovided at the central part of its bottom with a tubular depending part16, in which is removably secured a follower. 17 by a set-screw, 18,which follower is suited to the size of pipe under treatment.

The holes 19 formed in the feet 15 of the yoke 11 which constitute thereamer support, stated, have I openings 20 opening out laterallytherefrom, so that by simply loosening the bolts 20, the yoke and reamerthat the stem 13 which supports the rcamer is adjustable vertically inthc yoke, enables the operator to cut the thread on the pipe and reamout the bur at the same time, as will presently appear more clearly. 21designates the dicsone on each side of the pipe being operated uponeachdie having five cutting faces, a, b, on its periphery, each pair ofcutting-faces being located at a different distance from its axis fromeach and every other pair of cutting-faces, so that by a rotaryadjustment of the dies on the screw-bolts, 22, that secures them to theadjustable beds 23, either of the five cutting faces can be brought intouse, so that five different sizes of pipe can be cut or threaded withthe same dies. The dies are kept from turning on their bolts 22, bymeans of set screws 24, turned up through the beds 23, and at their endsentering sockets 24, formed in the bottom of the dies, which sockets aremade in front of each pair of cutting faces of the said dies.

The beds 23 are arranged between guides, 25 of the stock, and set screws26 tapped through upwardly extended lugs 27 at the ends of the stock,and bearing at their inner ends against the outer ends of the beds,comprise means whereby the beds may be adjusted inward, to adjust thedies to the desired cut, The setscrews 28 extending up through slots inthe stock and tapped into the beds operate to hold the beds in theiradjusted position. The rods or, pipes, 29 screwed into the ends of thestock 10 aiiord means for operating the utensil by rotating the stockand its appliances about the pipe.

By the hereinbefore described means and their mode of operation, it willbe seen that the implement is enabled to perform all of the functionsmentioned at the outset of this specification, and in doing this tosupport the advantages and conveniences ascribed to it. It is to benoted that the dies themselves are adjustable as well as beingadjustable on their supports or beds.

It is recognized that changes may be made in the form and arrangement ofparts comprising the invention without departing from the nature orspirit thereof.

What is claimed as the invention, is

A device of the type set forth comprising a stock formed with a centralopening and with spaced parallel longitudinal upstanding guides on eachside of said opening, beds mounted for sliding adjustment on each sideof said opening, adjusting screws mounted at the ends of said beds, andadapted to engage the same to adjust them inwith their connections maybe removed. The fact wardly with relation to said opening, said bedshaving openings extending vertically therethrough, screws projectedthrough said'stock andengaged in said lastnamed openings to hold saidbeds at selected positions to which they may be adjusted, cutting diespivotally mounted on said beds and having a plurality of cutting faces,said dies being mounted for pivotal adjustment so as to present selectedfaces over said openings, said dies having sockets extending from theunderneath surfaces thereof and screw posts threaded into said beds anddesigned for engagement 10 in selected ones of said sockets to hold saiddies at selected positions to which they may be adjusted.

In testimony whereof, I afiix my signature, in presence of twoWitnesses.
